What happens to your RSUs and stock options when your company is acquired

For a lot of people, equity is the biggest number in the deal and the least understood. The announcement says the buyer will pay a certain price per share. What that means for your shares depends on three documents most people have never read closely: your grant agreement, your company’s equity plan, and the merger agreement.

Here’s how to read them, and what the answers usually look like.

Where do I find out what happens to my equity?

In this order:

1. Your grant agreements. Each grant has its own. Look for a section called Change in Control or Corporate Transaction. This is where single-trigger or double-trigger acceleration lives. Read how change of control clauses work.
2. The equity plan. It usually gives the board broad power to decide what happens to awards in a deal: assume them, substitute new awards, cash them out, or accelerate them.
3. The merger agreement. For public companies it’s filed with the SEC, usually as an exhibit to an 8-K within days of the announcement. Search it for Treatment of Company Equity Awards. It spells out exactly what happens to each type of award.
4. Your equity portal and HR. After the deal is signed, expect an FAQ. Before then, nobody will be able to tell you much.

What happens to unvested RSUs?

There are four common outcomes. Morgan Stanley’s guide lays out the same list:

• Converted or rolled over. Your RSUs become RSUs in the buyer, at the deal’s exchange ratio, usually on the same vesting schedule. This is a common result when the buyer is a public company with its own equity program.
• Cashed out. You’re paid the deal value for some or all of them, either at closing or on the original vesting dates.
• Accelerated. Some or all vest early, at closing (single-trigger) or only if you’re also let go afterward (double-trigger). Performance awards are often paid at target or pro-rated.
• Canceled. Some deals simply cancel unvested awards, sometimes with a replacement grant from the buyer and sometimes without.

What happens to vested RSUs and shares I already own?

Once an RSU vests, it’s just stock, and you’re a shareholder like any other. At closing your shares are bought for cash, exchanged for the buyer’s shares, or a mix, on the same terms as everyone else’s. You don’t get a vote on the price, but you do get the same price.

What happens to my stock options?

Options are more complicated because they have an exercise (strike) price.

• In-the-money vested options are commonly cashed out for the spread: the deal price minus your exercise price, times the number of options. Or they’re converted into options on the buyer’s stock with an adjusted price and share count.
• Underwater options, with an exercise price above the deal price, may be canceled with no payment at all.
• Unvested options follow the same paths as unvested RSUs: converted, cashed out, accelerated or canceled.

If you hold incentive stock options (ISOs), the tax rules are different from non-qualified options, and a cash-out can change how they’re taxed. The IRS explains the two types. This is one place where an hour with a tax adviser pays for itself.

What happens to my ESPP?

Employee stock purchase plans usually end before the deal closes. A common approach is to end the current offering period early, buy shares with the contributions collected so far, and then terminate the plan. Watch for a notice with the final purchase date; that’s your last chance to change or stop contributions.

How are RSUs taxed in an acquisition?

It depends on what happens to them:

What happens	Typical tax effect
Unvested RSUs cashed out	Ordinary income, like wages. Withholding may not cover the full bill.
Unvested RSUs rolled over	Usually no immediate tax. Taxed as they vest, as before.
Vested shares sold for cash	A normal stock sale: capital gain or loss.
Vested shares exchanged in a tax-free swap	No tax at closing; your basis and holding period carry over.
Vested shares exchanged in a taxable deal	Capital gain on the difference, and your basis resets.

Source: Morgan Stanley at Work. If a large cash-out lands in one year, check whether your withholding covers it before April does.

Do I lose unvested equity if I’m laid off after the deal?

Usually yes, unless your grant has double-trigger acceleration. That’s the protection that matters most after an acquisition, because the first year is when roles get cut. If you have it, write down the protection window (often 12 to 24 months after closing) and the notice deadlines for resigning with good reason.

If you don’t have it, factor that into the retention conversation. Asking for your unvested equity to accelerate if your role is eliminated is a reasonable request, and it costs the buyer nothing if they keep you. See how to negotiate a retention bonus.

What should I do right now?

1. Download every grant agreement and your latest vesting schedule.
2. Find the merger agreement (for public companies, the 8-K exhibit) and read the equity section.
3. Write down what you’ll have at closing: vested shares, unvested awards, underwater options.
4. Check your double-trigger protection and its deadlines.
5. Plan for the taxes on any cash-out, especially if it lands in a high-income year.
